Caterina Colombini, o della cugina sedotta. Una ‘ricostruzione’ della figura di Caterina attraverso i testi
No full textIn this essay the author demonstrates that it is possible to “reconstruct” the figure of Caterina Colombini (1340?-1387) – Giovanni Colombini’s cousin – through a group of texts: the hagiography of Caterina, the letters sent to her by Giovanni Colombini and, finally, Giovanni’s biography written by Feo Belcari. The author divides his text into four parts: the first part analyzes the content of Caterina’s hagiography; the second examines the linguistic form of the hagiographic text; in the third, the author analyzes the latent meaning of the window, a symbolic place where Giovanni and Caterina converse on divine topics; in the last part, to conclude, the teachings that Giovanni gives to Catherine and her spiritual daughters – the Gesuate – are analyzed

Caterina Tarabotti Unveiled
No full textCaterina Tarabotti (1615–1693) never identified herself as a painter in contemporary
documents or claimed authorship of any picture with her signature. She would have
surely joined the ranks of the many anonymous women painters of her time, were
it not for the art critic and historian Marco Boschini (1602–1681). In his La Carta
del Navegar Pitoresco (1660), Boschini was the first to notice Caterina’s talents and
provide information about her life.1
Alluding to her namesake saint and surname,
Boschini infused the painter’s biography with lyric flair. A light coming out of the
Varotari workshop, Caterina was, according to Boschini, a virgin very gifted in
painting. She herself honored art with her achievements, which came effortlessly.
Comparing her to a silver lamp that never burns out, the author, with a sense of
optimism, concluded that Caterina would live forever and her name would bear
eternal light and splendor

Publisher Copyright: © 2021 by the author. Licensee MDPI, Basel, Switzerland.Organic light emitting transistors (OLETs) represent a relatively new technology platform in the field of optoelectronics. An OLET is a device with a two-fold functionality since it behaves as a thin-film transistor and at the same time can generate light under appropriate bias conditions. This Review focuses mainly on one of the building blocks of such device, namely the gate dielectrics, and how it is possible to engineer it to improve device properties and performances. While many findings on gate dielectrics can be easily applied to organic light emitting transistors, we here concentrate on how this layer can be exploited and engineered as an active tool for light manipulation in this novel class of optoelectronic devices.Peer reviewe

NanOx model: how to predict RBE for hadrontherapy
No full textInternational audienceHadrontherapyis becoming an attractive modality for cancer treatment, as the exponential increase in the number of dedicated facilities built over the past decades shows. The favorable depth-dose profile of protons is mostly exploited to eradicate localized tumors situated close to organs at risk, while the high biological effectiveness makes carbon ion beams more adequate than the conventional radiotherapy modalities to treat radioresistant cancers. Such an efficiency in cell killing is quantified through the RBE (relative biological effectiveness), which is a complex function of multiple parameters related to the incident particles, the irradiation conditions and the intrinsic properties of the biological system. Determining the value of RBE for every scenario is a challenging task that requires modeling to comply with the demands of a clinical environment. NanOx addresses some of the flaws in the models currently implemented in the treatment planning systems, and presents many innovative features.This model [1, 2] integrates the fully-stochastic nature of ionizing radiation by taking into account the fluctuations in the deposited energyboth at nanometric and micrometric scales. Moreover, it considers the accumulation of oxidative stress and sublethal damage via theproduction and diffusion of reactive chemical species. The prediction of cell survival probability for a wide LET range requires the determination of only 5 parameters issued from experimental measurements specific to the cell line. The results obtained forV79, CHO-K1 and HSG cells in response to monoenergetic beams of photons, protons and carbon ions are in good agreement with the experimental data. NanOxis able to describe the effectiveness of ions, including the overkill effect at high LET values. Moreover, the typical shoulder in cell survival curves is reproduced owing to the introduction of the chemical specific energy which varies with LET. These promising results incited us to perform further studies to test the model predictions in conditions that are closer to the clinical context, i.e., for spread-out Bragg peak irradiations. We are currently working on the production of tables of linear-quadratic parameters (α,β), which constitute the input for estimating cell survival to mixed fields in hadrontherapy facilities thanks to Kanai approximation [3].Finally, NanOx field of application may be extended to other innovative radiotherapy treatments, e.g photoactivation of nanoparticles or neutron capture therapy.[1] Cunha, M.; Monini, C.; Testa, E.; Beuve, M. “NanOx, a new model to predict cell survival in the context of particle therapy.” Phys.

Type 1 and type 2 cytokine profile in AIDS-Kaposi's sarcoma patients after highly active antiretroviral therapy
No full textRapid maxillary expansion for the treatment of nasal obstruction in children younger than 12 years.
No full textOBJECTIVE: To assess short- and long-term effects of rapid maxillary expansion (RME) on nasal flow in young children. Since RME has been reported to positively influence nasal obstruction in subjects with respiratory problems by reducing nasal resistance, a similar efficacy of RME could be expected in children with deciduous and/or mixed dentition who are affected by maxillary constriction and nasal obstruction from a different cause. DESIGN: Prospective study of children younger than 12 years, with different grades of malocclusion and oral breathing. Data included active anterior rhinomanometry in both the supine and orthostatic positions, as well as radiographic cephalometric measurements. SETTING: Tertiary care university hospital. Data were prospectively collected from 2005 to 2007. PATIENTS: Nasal flow and resistance were measured in 65 children younger than 12 years, with mixed or deciduous dentition and different grades of malocclusion and oral breathing. MAIN OUTCOME MEASURE: Efficacy of RME for resolution of maxillary constriction. RESULTS: After RME, an improvement of nasal flow and resistance has been recorded in patients, in the supine position, who presented both anterior and posterior obstruction. Less notable changes were shown in isolated forms of obstruction and in the orthostatic position. CONCLUSION: In cases of maxillary constriction and nasal airway obstruction, RME has proved to be efficient for the improvement of nasal respiration in children via a widening effect on the nasopharyngeal cavity
